Section 3.8 Powers and Duties of the Property Trustee. ----------------------------------------- (a) The legal title to the Subordinated Notes shall be owned by and held of record in the name of the Property Trustee for the benefit of the Trust and the Holders of the Securities. The right, title and interest of the Property Trustee to the Subordinated Notes shall vest automatically in each Person who may hereafter be appointed as Property Trustee as set forth in Section 5.6.

Funds in the Property Trustee Account shall be held uninvested until disbursed in accordance with this Declaration.

(e) The Property Trustee shall have the power to take any Legal Action which arises out of or in connection with an Event of Default or the Property Trustee's duties and obligations under this Declaration, the Business Trust Act or the Trust Indenture Act. If the Property Trustee fails to enforce its rights under the Subordinated Notes after a Holder of Preferred Securities has made a written request, such Holder may, to the fullest extent permitted by law, institute a legal proceeding against the Subordinated Notes Issuer, to enforce the Property Trustee's rights under the Subordinated Notes, without first instituting any legal proceeding against the Property Trustee or any other person or entity. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing and such event is attributable to the failure of the Subordinated Notes Issuer to pay interest, premium, if any, or principal on the Subordinated Notes on the date such interest, premium, if any, or principal is otherwise payable (or in the case of redemption, on the redemption date), then a Holder of Preferred Securities may directly institute a proceeding for enforcement of payment to such Holder of the principal of, premium, if any, or interest on, the Subordinated Notes having a principal amount equal to the aggregate liquidation amount of the Preferred Securities of such Holder (a "Direct Action"). Notwithstanding any payments made to such Holder of Preferred Securities by the Subordinated Notes Issuer in connection with a Direct Action, the Subordinated Notes Issuer shall remain obligated to pay the principal of, premium, if 16

any, or interest on the Subordinated Notes held by the Trust or the Property Trustee of the Trust, and the Subordinated Notes Issuer shall be subrogated to the rights of the Holder of such Preferred Securities with respect to payments on the Preferred Securities. Except as provided in the preceding sentences and in the Preferred Securities Guarantee, the Holders of Preferred Securities will not be able to exercise directly any other remedy available to the holders of the Subordinated Notes. (f) No resignation of the Property Trustee shall be effective unless either: (i) the Trust has been completely liquidated and the proceeds of the liquidation distributed to the Holders of Securities pursuant to the terms of the Securities; or (ii) a Successor Property Trustee has been appointed and accepted that appointment in accordance with Section 5.6. (g) The Property Trustee shall have the legal power to exercise all of the rights, powers and privileges of a holder of Subordinated Notes under the Indenture and, if an Event of Default occurs and is continuing, the Property Trustee shall, for the benefit of Holders of the Securities, enforce its rights as holder of the Subordinated Notes subject to the rights of the Holders pursuant to the terms of such Securities and this Declaration. (h) The Property Trustee may authorize one or more Persons (each, a "Paying Agent") to pay Distributions, redemption payments or liquidation payments on behalf of the Trust with respect to the Preferred Securities and any such Paying Agent shall comply with (S) 317(b) of the Trust Indenture Act. Any Paying Agent may be removed by the Property Trustee at any time and a successor Paying Agent or additional Paying Agents may be appointed at any time by the Property Trustee. (i) Subject to this Section 3.8, the Property Trustee shall have none of the powers or the authority of the Regular Trustees set forth in Section 3.6. (j) The Property Trustee must exercise the powers set forth in this Section 3.8 in a manner which is consistent with the purposes, functions and characterization for United States federal income tax purposes of the Trust set forth in Section 3.3 and the Property Trustee shall not take any action which is inconsistent with or contrary to the purposes, functions and characterization for United States federal income tax purposes of the Trust set out in Section 3.3.

In case an Event of Default has occurred (that has not been cured or waived pursuant to Section 2.6), the Property Trustee shall exercise such of the rights and powers vested in it by this Declaration, and use the same degree of care and skill in their exercise or use, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs; (b) no provision of this Declaration shall be construed to relieve the Property Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (i) this Subsection shall not be construed to limit Subsection (a) of this Section; (ii) the Property Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer of the Property Trustee, unless it shall be proved that the Property Trustee was negligent in ascertaining the pertinent facts; (iii) the Property Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of not less than a Majority in liquidation amount of the Securities at the time outstanding relating to the time, method and place of conducting any proceeding for any remedy available to the Property Trustee, or exercising any trust or power conferred upon the Property Trustee under this Declaration including, without limitation, with respect to the Securities; and (iv) no provision of this Declaration shall require the Property Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

Any Trustee may resign from office (without need for prior or subsequent accounting) by an instrument in writing signed by the Trustee and delivered to the Sponsor and the Trust, which resignation shall take effect upon such delivery or upon such later date as is specified therein; provided, however, that: (i) no such resignation of the Trustee that acts as the Property Trustee shall be effective (A) until a Successor Property Trustee has been appointed and has accepted such appointment by instrument executed by such Successor Property Trustee and delivered to the Trust, the Sponsor and the resigning Property Trustee; or (B) until the assets of the Trust have been completely liquidated and the proceeds thereof distributed to the holders of the Securities; and 26

(ii) so long as a Delaware Trustee is required pursuant to Section 5.1, no such resignation of the Trustee that acts as the Delaware Trustee shall be effective until a Successor Delaware Trustee has been appointed and has accepted such appointment by instrument executed by such Successor Delaware Trustee and delivered to the Trust, the Sponsor and the resigning Delaware Trustee. (d) The Holders of the Common Securities shall use their best efforts to promptly appoint a Successor Delaware Trustee (so long as a Delaware Trustee is required pursuant to Section 5.1) or Successor Property Trustee, as the case may be, if the Property Trustee or the Delaware Trustee delivers an instrument of resignation in accordance with this Section 5.6. (e) If no Successor Property Trustee or Successor Delaware Trustee shall have been appointed and accepted appointment as provided in this Section 5.6 within 60 days after delivery of an instrument of resignation or removal, the Property Trustee or Delaware Trustee resigning or being removed may petition any court of competent jurisdiction for appointment of a Successor Property Trustee or Successor Delaware Trustee. Such court may thereupon after such notice, if any, as it may deem proper and prescribe, appoint a Successor Property Trustee or Successor Delaware Trustee, as the case may be. Section 5.7 Vacancies Among Trustees. ------------------------ If a Trustee ceases to hold office for any reason and the number of Trustees is not reduced pursuant to Section 5.1, or if the number of Trustees is increased pursuant to Section 5.1, a vacancy shall occur. A resolution certifying the existence of such vacancy by a majority of the Regular Trustees shall be conclusive evidence of the existence of such vacancy. The vacancy shall be filled with a Trustee appointed in accordance with Section 5.6. Section 5.8 Effect of Vacancies. ------------------- The death, resignation, retirement, removal, bankruptcy, dissolution, liquidation, incompetence or incapacity to perform the duties of a Trustee, or any one of them, shall not operate to annul the Trust. Whenever a vacancy in the number of Regular Trustees shall occur, until such vacancy is filled by the appointment of a Regular Trustee in accordance with Section 5.6, the Regular Trustees in office, regardless of their number, shall have all the powers granted to the Regular Trustees and shall discharge all the duties imposed upon the Regular Trustees by this Declaration. Section 5.9 Meetings. -------- Meetings of the Regular Trustees shall be held from time to time upon the call of any Regular Trustee. Regular meetings of the Regular Trustees may be held at a time and place fixed by resolution of the Regular Trustees. Notice of any in-person meetings of the Regular Trustees shall be hand delivered or otherwise delivered in writing (including by facsimile, with a hard copy by overnight courier) not less than 48 hours before such meeting. Notice of any telephonic meetings of the Regular Trustees or any committee thereof shall be hand delivered or otherwise delivered in writing (including by facsimile, with a hard copy by overnight courier) not less than 24 hours before a meeting. Notices shall contain a brief statement of the time, place and anticipated purposes of the meeting. The presence (whether in person or by telephone) of a 27

Regular Trustee at a meeting shall constitute a waiver of notice of such meeting except where a Regular Trustee attends a meeting for the express purpose of objecting to the transaction of any activity on the ground that the meeting has not been lawfully called or convened. Unless provided otherwise in this Declaration, any action of the Regular Trustees may be taken at a meeting by vote of a majority of the Regular Trustees present (whether in person or by telephone) and eligible to vote with respect to such matter, provided that a Quorum is present, or without a meeting by the unanimous written consent of the Regular Trustees. Section 5.10 Delegation of Power. ------------------- (a) Any Regular Trustee may, by power of attorney consistent with applicable law, delegate to any other natural person over the age of 21 his or her power for the purpose of executing any documents contemplated in Section 3.6 including any registration statement or amendment thereto filed with the Commission or making any other governmental filing. (b) The Regular Trustees shall have power to delegate from time to time to such of their number or to officers of the Trust the doing of such things and the execution of such instruments either in the name of the Trust or the names of the Regular Trustees or otherwise as the Regular Trustees may deem expedient, to the extent such delegation is not prohibited by applicable law or contrary to the provisions of the Trust, as set forth herein. Section 5.11 Merger, Conversion, Consolidation or Succession to Business. ----------------------------------------------------------- Any corporation into which the Property Trustee or the Delaware Trustee, as the case may be, may be merged or converted or with which either may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Property Trustee or the Delaware Trustee, as the case may be, shall be bound by this Declaration, or any corporation succeeding to all or substantially all the corporate trust business of the Property Trustee or the Delaware Trustee, as the case may be, shall be the successor of the Property Trustee or the Delaware Trustee, as the case may be, hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. ARTICLE VI DISTRIBUTIONS Section 6.1 Distributions. ------------- Holders shall receive Distributions in accordance with the applicable terms of the relevant Holder's Securities. Distributions shall be made on the Preferred Securities and the Common Securities in accordance with the preferences set forth in their respective terms. If and to the extent that the Subordinated Notes Issuer makes a payment of interest (including Additional Interest (as defined in the Indenture)), premium, if any, and principal on the Subordinated Notes held by the Property Trustee (the amount of any such payment being a "Payment Amount"), the Property Trustee shall and is directed, to the extent funds are available for that purpose, to make a distribution (a "Distribution") of the Payment Amount to Holders. In 28

the event the Sponsor shall defer any payment of principal, premium, if any, or interest on the Subordinated Notes, the Trust shall, in like manner, defer payments of Distributions on the Securities, and additional Distributions shall accrue on such Securities for so long as the payment of principal, premium, if any, or interest on the Subordinated Notes is deferred. ARTICLE VII ISSUANCE OF SECURITIES Section 7.1 General Provisions Regarding Securities. --------------------------------------- (a) The Regular Trustees shall, on behalf of the Trust, issue one class of preferred securities representing undivided beneficial interests in the assets of the Trust having such terms as are set forth in Exhibit A and incorporated herein by reference (the "Preferred Securities"), and one class of common securities representing undivided beneficial interests in the assets of the Trust having such terms as are set forth in Exhibit A and incorporated herein by reference (the "Common Securities"). The Trust shall have no securities or other interests in the assets of the Trust other than the Preferred Securities and the Common Securities; (b) the Certificates shall be signed on behalf of the Trust by the Regular Trustees (or if there are more than two Regular Trustees by any two of the Regular Trustees). Such signatures may be the manual or facsimile signatures of the present or any future Regular Trustee. Typographical and other minor errors or defects in any such reproduction of any such signature shall not affect the validity of any Certificate. In case any Regular Trustee of the Trust who shall have signed any of the Certificates shall cease to be such Regular Trustee before the Certificate so signed shall be delivered by the Trust, such Certificate nevertheless may be delivered as though the person who signed such Certificate had not ceased to be such Regular Trustee; and any Certificate may be signed on behalf of the Trust by such persons who shall at the actual date of execution of such Security, be the Regular Trustees of the Trust, although at the date of the execution and delivery of the Declaration any such person was not such a Regular Trustee. Certificates shall be printed, lithographed or engraved or may be produced in any other manner as is reasonably acceptable to the Regular Trustees, as evidenced by their execution thereof, and may have such letters, numbers or other marks of identification or designation and such legends or endorsements as the Regular Trustees may deem appropriate, or as may be required to comply with any law or with any rule or regulation of any stock exchange on which Securities may be listed, or to conform to usage. A Preferred Security shall not be valid until authenticated by the manual signature of an authorized signatory of the Property Trustee. The signature shall be conclusive evidence that the Preferred Security has been authenticated under this Declaration. Upon a written order of the Trust signed by one Regular Trustee, the Property Trustee shall authenticate the Preferred Securities for original issue. The Property Trustee may appoint an authenticating agent acceptable to the Trust to authenticate Preferred Securities. An authenticating agent may authenticate Preferred Securities whenever the Property Trustee may do so. Each reference in this Declaration to authentication by the Property Trustee includes authentication by such agent. An authenticating agent has the same rights as the Property Trustee to deal with the Trust or an Affiliate; 29

(c) the consideration received by the Trust for the issuance of the Securities shall constitute a contribution to the capital of the Trust and shall not constitute a loan to the Trust; (d) upon issuance of the Securities as provided in this Declaration, the Securities so issued shall be deemed to be validly issued, fully paid and nonassessable; and (e) every Person, by virtue of having become a Holder or a Preferred Security Beneficial Owner in accordance with the terms of this Declaration, shall be deemed to have expressly assented and agreed to the terms of, and shall be bound by this Declaration. ARTICLE VIII DISSOLUTION AND TERMINATION OF TRUST Section 8.1 Dissolution and Termination of Trust. ------------------------------------ (a) The Trust shall dissolve and its affairs shall be wound up, upon the earliest to occur of the following: (i) upon the bankruptcy of the Sponsor or the Holder of the Common Securities; (ii) upon the filing of a certificate of dissolution or its equivalent with respect to the Sponsor, the filing of a certificate of cancellation with respect to the Trust upon the consent (other than in connection with a dissolution of the Trust pursuant to clause (v) of this Section 8.1(a)) of the Holders of at least a Majority in liquidation amount of the Securities, voting together as a single class, to file such certificate of cancellation, or the revocation of the charter of the Sponsor or the Holder of the Common Securities and the expiration of 90 days after the date of revocation without a reinstatement thereof; (iii) upon the entry of a decree of judicial dissolution of the Sponsor or the Trust or the Holder of the Common Securities; (iv) when all of the Securities shall have been called for redemption and the amounts necessary for redemption thereof shall have been paid to the Holders in accordance with the terms of the Securities; (v) upon the election by the Sponsor, effective upon notice to the Trust, the Property Trustee and the Delaware Trustee, to dissolve the Trust in accordance with the terms of the Securities and all of the Subordinated Notes held by the Property Trustee shall have been distributed to the Holders of Securities in exchange for all of the Securities; (vi) upon the written direction to the Property Trustee from the Sponsor at any time to terminate the Trust and, after satisfaction of liabilities to creditors of the Trust as provided by applicable law, the distribution of Subordinated Notes to Holders in exchange for the Securities, subject to the Regular Trustees' receipt of an opinion of 30

counsel experienced in such matters to the effect that the Holders of the Preferred Securities will not recognize any income, gain or loss for United States federal income tax purposes as a result of the dissolution of the Trust and such distribution to Holders; or (vii) before the issuance of any Securities, with the consent of all of the Regular Trustees and the Sponsor; and (b) As soon as is practicable after the occurrence of an event referred to in Section 8.1(a) or dissolution pursuant to Section 3.14 and upon the completion of the winding up of the Trust, one of the Regular Trustees (each Regular Trustee being hereby authorized to take such action) shall file a certificate of cancellation with the Secretary of State of the State of Delaware terminating the Trust. (c) The provisions of Section 3.9 and Article X shall survive the termination of the Trust. ARTICLE IX TRANSFER OF INTERESTS Section 9.1 Transfer of Securities. ---------------------- (a) Securities may only be transferred, in whole or in part, in accordance with the terms and conditions set forth in this Declaration and in the terms of the Securities. Any transfer or purported transfer of any Security not made in accordance with this Declaration shall be null and void; (b) subject to this Article IX, Preferred Securities shall be freely transferable; and (c) subject to this Article IX, the Sponsor and any Related Party may only transfer Common Securities to the Sponsor or a Related Party of the Sponsor; provided that, any such transfer shall not violate the Securities Act and is subject to the condition precedent that the transferor obtain the written opinion of counsel experienced in such matters that such transfer would not cause more than an insubstantial risk that: (i) the Trust would not be classified for United States federal income tax purposes as a grantor trust; and (ii) the Trust would be an Investment Company required to register under the Investment Company Act or the transferee would become an Investment Company required to register under the Investment Company Act. (d) Each Common Security that bears or is required to bear the legend set forth in this Section 9.1(d) shall be subject to the restrictions on transfer provided in the legend set forth in this Section 9.1(d), unless such restrictions on transfer shall be waived by the written consent of the Regular Trustees, and the Holder of each such Common Security, by such security holder's acceptance thereof, agrees to be bound by such restrictions on transfer. As used in this 31

Section 9.1(d) and in Section 9.1(c), the term "transfer" encompasses any sale, pledge, transfer or other disposition of any such Common Security. Any certificate evidencing a Common Security shall bear a legend in substantially the following form, unless otherwise agreed by the Regular Trustees (with written notice thereof to the Property Trustee): THE SECURITY EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD UNLESS SUCH OFFER AND SALE ARE REGISTERED UNDER OR ARE EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT. THE TRANSFER OF THE SECURITY EVIDENCED HEREBY IS ALSO SUBJECT TO THE RESTRICTIONS SET FORTH IN THE DECLARATION REFERRED TO BELOW. Section 9.2 Transfer of Certificates. ------------------------ (a) The Regular Trustees shall provide for the registration of Certificates and of transfers of Certificates, which will be effected without charge but only upon payment (with such indemnity as the Regular Trustees may require) in respect of any tax or other government charges which may be imposed in relation to it. Upon surrender for registration of transfer of any Certificate, the Regular Trustees shall cause one or more new Certificates to be issued in the name of the designated transferee or transferees. Every Certificate surrendered for registration of transfer shall be accompanied by a written instrument of transfer in form satisfactory to the Regular Trustees duly executed by the Holder or such Holder's attorney duly authorized in writing. Each Certificate surrendered for registration of transfer shall be canceled by the Regular Trustees. A transferee of a Certificate shall be entitled to the rights and subject to the obligations of a Holder hereunder upon the receipt by such transferee of a Certificate. By acceptance of a Certificate, each transferee shall be deemed to have agreed to be bound by this Declaration and the documents incorporated by reference herein. (b) Notwithstanding any other provisions of this Declaration, a Global Certificate may not be transferred as a whole, except by the Clearing Agency to a nominee of the Clearing Agency or by the Clearing Agency or any such nominee to a successor Clearing Agency or a nominee of such successor Clearing Agency. Section 9.3 Deemed Security Holders. ----------------------- The Trustees may treat the Person in whose name any Certificate shall be registered on the books and records of the Trust as the sole holder of such Certificate and of the Securities represented by such Certificate for purposes of receiving Distributions and for all other purposes whatsoever and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such Certificate or in the Securities represented by such Certificate on the part of any Person, whether or not the Trustees shall have actual or other notice thereof. 32

Section 9.4 Book Entry Interests. -------------------- (a) So long as Preferred Securities are eligible for book entry settlement with the Clearing Agency or unless otherwise required by law, all Preferred Securities that are so eligible may be represented by one or more, fully registered, global Preferred Security Certificates (each a "Global Certificate"), to be delivered to DTC, the initial Clearing Agency, by, or on behalf of, the Trust. Such Global Certificates shall initially be registered on the books and records of the Trust in the name of Cede & Co., the nominee of DTC, and no Preferred Security Beneficial Owner will receive a definitive Preferred Security Certificate representing such Preferred Security Beneficial Owner's interests in such Global Certificates, except as provided in Section 9.7. The transfer and exchange of beneficial interests in any such Security in global form shall be effected through the Clearing Agency in accordance with this Declaration and the procedures of the Clearing Agency therefor. (b) Except as provided below, Beneficial Owners of a Preferred Security in global form shall not be entitled to have certificates registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form and will not be considered Holder of such Preferred Security in global form. (c) Any Global Certificate may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of this Declaration as may be required by the Clearing Agency, by any national securities exchange or by the National Association of Securities Dealers, Inc. as may be required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or interdealer quotation system upon which the Preferred Securities may be listed or traded or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Preferred Securities are subject. (d) Unless and until definitive, fully registered Preferred Security Certificates (the "Definitive Preferred Security Certificates") have been issued to the Preferred Security Beneficial Owners pursuant to Section 9.7: (i) the provisions of this Section 9.4 shall be in full force and effect with respect to such Preferred Securities; (ii) the Trust and the Trustees shall be entitled to deal with the Clearing Agency for all purposes of this Declaration (including the payment of Distributions on the Global Certificates and receiving approvals, votes or consents hereunder) as the Holder of the Preferred Securities and the sole holder of the Global Certificates and shall have no obligation to the Preferred Security Beneficial Owners; (iii) to the extent that the provisions of this Section 9.4 conflict with any other provisions of this Declaration, the provisions of this Section 9.4 shall control; and (iv) the rights of the Beneficial Owners of Preferred Securities in global form shall be exercised only through the Clearing Agency and shall be limited to those established by law and agreements between such Preferred Security Beneficial Owners and the Clearing Agency and/or the Clearing Agency Participants. The Clearing Agency 33

will make book entry transfers among the Clearing Agency Participants and receive and transmit payments of Distributions on the Global Certificates to such Clearing Agency Participants. DTC will make book entry transfers among the Clearing Agency Participants, provided, that solely for the purposes of determining whether the Holders of the requisite amount of Preferred Securities have voted on any matter provided for in this Declaration, so long as Definitive Preferred Security Certificates have not been issued, the Trustees may conclusively rely on, and shall be protected in relying on, any written instrument (including a proxy) delivered to the Trustees by the Clearing Agency setting forth the Preferred Securities Beneficial Owners' votes or assigning the right to vote on any matter to any other Persons either in whole or in part. Notwithstanding any other provisions of this Declaration (other than the provisions set forth in this Section 9.4(d)), a Preferred Security in global form may not be transferred as a whole except by the Clearing Agency to a nominee of the Clearing Agency or by a nominee of the Clearing Agency to the Clearing Agency or another nominee to a successor Clearing Agency or a nominee of such successor Clearing Agency. Section 9.5 Notices to Clearing Agency. -------------------------- Whenever a notice or other communication to the Preferred Security Holders is required under this Declaration, unless and until Definitive Preferred Security Certificates shall have been issued to the Preferred Security Beneficial Owners pursuant to Section 9.7, the Trustees shall give all such notices and communications, specified herein to be given to the Preferred Security Holders, to the Clearing Agency, and shall have no notice obligations to the Preferred Security Beneficial Owners. Section 9.6 Appointment of Successor Clearing Agency. ---------------------------------------- If any Clearing Agency notifies the Trust that it is unwilling or unable to continue its services as securities depositary with respect to the Preferred Securities if such Clearing Agency ceases to perform such services, or if at any time such Clearing Agency ceases to be a clearing agency registered as such under the Exchange Act when such Clearing Agency is required to be so registered to act as such depositary, then the Regular Trustees may, in their sole discretion, appoint a successor Clearing Agency with respect to such Preferred Securities. Section 9.7 Definitive Preferred Security Certificates Under Certain -------------------------------------------------------- Circumstances. - ------------- If: (a) a Clearing Agency notifies the Trust that it is unwilling or unable to continue its services as securities depositary with respect to the Preferred Securities, if such Clearing Agency ceases to perform such services, or if at any time such Clearing Agency ceases to be a clearing agency registered as such under the Exchange Act when such Clearing Agency is required to be so registered to act as such depositary, and a successor Clearing Agency is not appointed within 90 days after such discontinuance pursuant to Section 9.6; or 34

(b) the Regular Trustees (with the consent of the Sponsor) in their sole discretion determine that the Preferred Securities in global form shall be exchanged for certificated Preferred Securities; then: (i) Definitive Preferred Security Certificates shall be prepared by the Regular Trustees on behalf of the Trust with respect to such Preferred Securities; and (ii) upon surrender of the Global Certificates by the Clearing Agency, accompanied by registration instructions, the Regular Trustees shall cause Definitive Preferred Security Certificates to be delivered to Preferred Security Beneficial Owners of such Preferred Securities in accordance with the instructions of the Clearing Agency. Neither the Trustees nor the Trust shall be liable for any delay in delivery of such instructions and each of them may conclusively rely on and shall be protected in relying on, said instructions of the Clearing Agency. The Definitive Preferred Security Certificates shall be printed, lithographed or engraved or may be produced in any other manner as is reasonably acceptable to the Regular Trustees, as evidenced by their execution thereof, and may have such letters, numbers or other marks of identification or designation and such legends or endorsements as the Regular Trustees may deem appropriate, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which Preferred Securities may be listed, or to conform to usage. At such time as all interests in a Preferred Security in global form have been redeemed, exchanged, repurchased or canceled, such Preferred Security in global form shall be, upon receipt thereof, canceled by the Trust in accordance with standing procedures and instructions of the Clearing Agency. Section 9.8 Mutilated, Destroyed, Lost or Stolen Certificates. ------------------------------------------------- If: (a) any mutilated Certificates should be surrendered to the Regular Trustees, or if the Regular Trustees shall receive evidence to their satisfaction of the destruction, loss or theft of any Certificate; and (b) there shall be delivered to the Property Trustee or the Regular Trustees such security or indemnity as may be required by them to keep each of them harmless, then: in the absence of notice that such Certificate shall have been acquired by a bona fide purchaser, the Property Trustee or any Regular Trustee on behalf of the Trust shall execute and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like denomination. In connection with the issuance of any new Certificate under this Section 9.8, the Property Trustee or the Regular Trustees may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection 35

therewith. Any duplicate Certificate issued pursuant to this Section shall constitute conclusive evidence of an ownership interest in the relevant Securities, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time. ARTICLE X LIMITATION OF LIABILITY OF HOLDERS OF SECURITIES, TRUSTEES OR OTHERS Section 10.1 Liability. --------- (a) Except as expressly set forth in this Declaration, the Preferred Securities Guarantee, the Common Securities Guarantee and the terms of the Securities, the Sponsor shall not be: (i) personally liable for the return of any portion of the capital contributions (or any return thereon) of the Holders of the Securities, which shall be made solely from assets of the Trust; or (ii) be required to pay to the Trust or to any Holder of Securities any deficit upon dissolution of the Trust or otherwise. (b) Pursuant to (S) 3803(a) of the Business Trust Act, the Holders of the Securities, in their capacity as such, shall be entitled to the same limitation of personal liability extended to stockholders of private corporations for profit organized under the General Corporation Law of the State of Delaware. Section 10.2 Exculpation. ----------- (a) No Indemnified Person shall be liable, responsible or accountable in damages or otherwise to the Trust or any Covered Person for any loss, damage or claim incurred by reason of any act or omission performed or omitted by such Indemnified Person in good faith on behalf of the Trust and in a manner such Indemnified Person reasonably believed to be within the scope of the authority conferred on such Indemnified Person by this Declaration or by law, except that an Indemnified Person shall be liable for any such loss, damage or claim incurred by reason of such Indemnified Person's negligence (or, in the case of the Property Trustee, except as otherwise set forth in Section 3.9) or willful misconduct with respect to such acts or omissions. (b) An Indemnified Person shall be fully protected in relying in good faith upon the records of the Trust and upon such information, opinions, reports or statements presented to the Trust by any Person as to matters the Indemnified Person reasonably believes are within such other Person's professional or expert competence and who has been selected with reasonable care by or on behalf of the Trust, including information, opinions, reports or statements as to the value and amount of the assets, liabilities, profits, losses, or any other facts pertinent to the existence and amount of assets from which Distributions to Holders of Securities might properly be paid. 36

Section 10.3 Fiduciary Duty. -------------- (a) To the extent that, at law or in equity, an Indemnified Person has duties (including fiduciary duties) and liabilities relating thereto to the Trust or to any other Covered Person, an Indemnified Person acting under this Declaration shall not be liable to the Trust or to any other Covered Person for its good faith reliance on the provisions of this Declaration. The provisions of this Declaration, to the extent that they restrict the duties and liabilities of an Indemnified Person otherwise existing at law or in equity (other than duties imposed on the Property Trustee under the Trust Indenture Act), are agreed by the parties hereto to replace such other duties and liabilities of such Indemnified Person; (b) Unless otherwise expressly provided herein: (i) whenever a conflict of interest exists or arises between an Indemnified Person and any Covered Persons; or (ii) whenever this Declaration or any other agreement contemplated herein or therein provide that an Indemnified Person shall act in a manner that is, or provides terms that are, fair and reasonable to the Trust or any Holder of Securities, the Indemnified Person shall resolve such conflict of interest, take such action or provide such terms, considering in each case the relative interest of each party (including its own interest) to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interests, any customary or accepted industry practices, and any applicable generally accepted accounting practices or principles. In the absence of bad faith by the Indemnified Person, the resolution, action or term so made, taken or provided by the Indemnified Person shall not constitute a breach of this Declaration or any other agreement contemplated herein or of any duty or obligation of the Indemnified Person at law or in equity or otherwise. (c) Whenever in this Declaration an Indemnified Person is permitted or required to make a decision: (i) in its "discretion" or under a grant of similar authority, the Indemnified Person shall be entitled to consider such interests and factors as it desires, including its own interests, and shall have no duty or obligation to give any consideration to any interest of or factors affecting the Trust or any other Person; or (ii) in its "good faith" or under another express standard, the Indemnified Person shall act under such express standard and shall not be subject to any other or different standard imposed by this Declaration or by applicable law. Section 10.4 Indemnification. --------------- (a) The Sponsor shall indemnify each Indemnified Person for, and hold each Indemnified Person harmless against, any loss, liability or expense incurred by such Indemnified Person by reason of any act or omission performed or omitted by such Indemnified Person without negligence or bad faith (or, in case of the Property Trustee, except as set forth in Section 37

3.9) on behalf of the Trust and in a manner such Indemnified Person reasonably believed to be within the scope of authority conferred on such Indemnified Person by this Declaration; (b) reasonable expenses (including reasonable legal fees and expenses) incurred by an Indemnified Person in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Sponsor prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Sponsor of an undertaking by or on behalf of the Indemnified Person to repay such amount if it shall be determined that the Indemnified Person is not entitled to be indemnified as authorized in Section 10.4(a); and (c) the provisions of this Section 10.4 shall survive the termination of this Declaration or resignation or removal of any Trustee. Section 10.5 Outside Businesses. ------------------ Any Covered Person, the Sponsor, the Delaware Trustee and the Property Trustee (subject to Section 5.3(c)) may engage in or possess an interest in other business ventures of any nature or description, independently or with others, similar or dissimilar to the business of the Trust, and the Trust and the Holders of Securities shall have no rights by virtue of this Declaration in and to such independent ventures or the income or profits derived therefrom, and the pursuit of any such venture, even if competitive with the business of the Trust, shall not be deemed wrongful or improper. No Covered Person, the Sponsor, the Delaware Trustee, or the Property Trustee shall be obligated to present any particular investment or other opportunity to the Trust even if such opportunity is of a character that, if presented to the Trust, could be taken by the Trust, and any Covered Person, the Sponsor, the Delaware Trustee and the Property Trustee shall have the right to take for its own account (individually or as a partner or fiduciary) or to recommend to others any such particular investment or other opportunity. Any Covered Person, the Delaware Trustee and the Property Trustee may engage or be interested in any financial or other transaction with the Sponsor or any Affiliate of the Sponsor, or may act as depositary for, trustee or agent for, or act on any committee or body of holders of, securities or other obligations of the Sponsor or its Affiliates.

Section 11.2 Certain Accounting Matters. -------------------------- (a) At all times during the existence of the Trust, the Trust shall keep, or cause to be kept, full books of account, records and supporting documents, which shall reflect in reasonable detail, each transaction of the Trust. The books of account shall be maintained on the accrual method of accounting, in accordance with generally accepted accounting principles, consistently 38

applied. The Trust shall use the accrual method of accounting for United States federal income tax purposes.

(b) The Trust shall cause to be duly prepared and delivered to each of the Holders of Securities, any annual United States federal income tax information statement, required by the Code, containing such information with regard to the Securities held by each Holder as is required by the Code and the Treasury Regulations. Notwithstanding any right under the Code to deliver any such statement at a later date, the Trust shall endeavor to deliver all such statements within 30 days after the end of each Fiscal Year of the Trust. (c) The Trust shall cause to be duly prepared and filed with the appropriate taxing authority, an annual United States federal income tax return, on a Form 1041 or such other form required by United States federal income tax law, and any other annual income tax returns required to be filed by the Trust on behalf of the Trust with any state or local taxing authority. Section 11.3 Banking. ------- The Trust shall maintain one or more bank accounts in the name and for the sole benefit of the Trust; provided, however, that all payments of funds in respect of the Subordinated Notes held by the Property Trustee shall be made directly to the Property Trustee Account and no other funds of the Trust shall be deposited in the Property Trustee Account. The sole signatories for such accounts shall be designated by the Regular Trustees; provided, however, that the Property Trustee shall designate the signatories for the Property Trustee Account. Section 11.4 Withholding. ----------- The Trust shall comply with all withholding requirements under United States federal, state and local law.

To the extent that the Trust is required to withhold and pay over any amounts to any authority with respect to distributions or allocations to any Holder, the amount withheld shall be deemed to be a distribution in the amount of the withholding to the Holder.

EXHIBIT A TERMS OF 8.16% TRUST ORIGINATED PREFERRED SECURITIES 8.16% TRUST ORIGINATED COMMON SECURITIES Pursuant to Section 7.1 of the Amended and Restated Declaration of Trust, dated as of January 20, 1999 (as amended from time to time, the "Declaration"), the designation, rights, privileges, restrictions, preferences and other terms and provisions of the Preferred Securities and the Common Securities are set out below (each capitalized term used but not defined herein has the meaning set forth in the Declaration or, if not defined in such Declaration, as defined in the Prospectus referred to below): 1. Designation and Number. ---------------------- a. Preferred Securities. 21,000,000 Preferred Securities of the -------------------- Trust with an aggregate liquidation amount with respect to the assets of the Trust of Five Hundred Twenty-Five Million Dollars ($525,000,000), and a liquidation amount with respect to the assets of the Trust of $25 per Preferred Security, are hereby designated for the purposes of identification only as "8.16% Trust Originated Preferred Securities" (the "Preferred Securities"). The Preferred Security Certificates evidencing the Preferred Securities shall be substantially in the form attached hereto as Annex I, with such changes and additions thereto or deletions therefrom as may be required by ordinary usage, custom or practice or to conform to the rules of any stock exchange on which the Preferred Securities are listed. b. Common Securities. 649,485 Common Securities of the Trust with an ----------------- aggregate liquidation amount with respect to the assets of the Trust of Sixteen Million Two Hundred Thirty-Seven Thousand One Hundred Twenty-Five Dollars ($16,237,125), and a liquidation amount with respect to the assets of the Trust of $25 per Common Security, are hereby designated for the purposes of identification only as "8.16% Trust Originated Common Securities" (the "Common Securities"). The Common Security Certificates evidencing the Common Securities shall be substantially in the form attached hereto as Annex II, with such changes and additions thereto or deletions therefrom as may be required by ordinary usage, custom or practice. 2. Distributions. ------------- a. Periodic Distributions payable on each Security will be fixed at a rate per annum of 8.16% (the "Coupon Rate") of the stated liquidation amount of $25 per Security, such rate being the rate of interest payable on the Subordinated Notes to be held by the Property Trustee. Distributions in arrears for more than one quarterly period will bear interest thereon at the Coupon Rate (to the extent permitted by applicable law). The term "Distributions" as used in these terms includes such periodic cash distributions and any such interest payable unless otherwise stated. A Distribution is payable only to the extent that payments are made in respect of the Subordinated Notes held by the Property Trustee. The amount of Distributions payable for any period will be computed for any full quarterly Distribution period on the basis of a 360-day year of twelve 30-day months, and for any period shorter than a full quarterly Distribution period A-1

for which Distributions are computed, Distributions will be computed on the basis of the actual number of days elapsed in such a 30-day month. b. Distributions on the Securities will be cumulative, will accrue from January 20, 1999 and will be payable quarterly in arrears, on March 31, June 30, September 30 and December 31 of each year, commencing on March 31, 1999, except as otherwise described below. The Subordinated Notes Issuer has the right under the Indenture to defer payments of interest by extending the interest payment period from time to time on the Subordinated Notes for a period not exceeding 20 consecutive quarterly periods (each, an "Extension Period") but not beyond the maturity date of the Subordinated Notes and, as a consequence of such extension, Distributions will also be deferred. Despite such deferral, quarterly Distributions will continue to accrue with interest thereon (to the extent permitted by applicable law) at the Coupon Rate during any such Extension Period. Prior to the termination of any such Extension Period, the Subordinated Notes Issuer may further extend such Extension Period; provided that such Extension Period together with all such previous and further extensions thereof may not exceed 20 consecutive quarterly periods. Payments of accrued Distributions will be payable to Holders as they appear on the books and records of the Trust on the first record date after the end of the Extension Period. Upon the termination of any Extension Period and the payment of all amounts then due, the Subordinated Notes Issuer may commence a new Extension Period, subject to the above requirements. c. Distributions on the Securities will be payable to the Holders thereof as they appear on the books and records of the Trust on the relevant record dates. While the Preferred Securities remain in book entry only form, the relevant record dates shall be one Business Day prior to the relevant payment dates which payment dates correspond to the interest payment dates on the Subordinated Notes. Subject to any applicable laws and regulations and the provisions of the Declaration, each such payment in respect of the Preferred Securities will be made as described under the heading "Certain Terms of the Preferred Securities -- Book-Entry-Only Issuance -- The Depository Trust Company" in the Prospectus Supplement dated January 13, 1999 (the "Prospectus Supplement") to the Prospectus dated January 8, 1999 (as so supplemented the "Prospectus") of the Trust included in the Registration Statement on Form S-3 of the Sponsor, the Trust and certain other business trusts. The relevant record dates for the Common Securities shall be the same record dates as for the Preferred Securities. If the Preferred Securities shall not continue to remain in book entry only form, the relevant record dates for the Preferred Securities, shall conform to the rules of any securities exchange on which the securities are listed and, if none, shall be the 15/th/ day of the last month of each quarterly distribution period, even if that day is not a Business Day. Distributions payable on any Securities that are not punctually paid on any Distribution payment date, as a result of the Subordinated Notes Issuer having failed to make a payment under the Subordinated Notes, will cease to be payable to the Person in whose name such Securities are registered on the relevant record date, and such defaulted Distribution will instead be payable to the Person in whose name such Securities are registered on the special record date or other specified date determined in accordance with the Indenture. If any date on which Distributions are payable on the Securities is not a Business Day, then payment of the Distribution payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day is in the next succeeding calendar year, such payment shall be A-2

made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. d. In the event that there is any money or other property held by or for the Trust that is not accounted for hereunder, such property shall be distributed Pro Rata (as defined herein) among the Holders of the Securities. 3. Liquidation Distribution Upon Dissolution. ----------------------------------------- In the event of any voluntary or involuntary dissolution, winding-up or termination of the Trust, the Holders of the Securities on the date of the dissolution, winding-up or termination, as the case may be, will be entitled to receive out of the assets of the Trust available for distribution to Holders of Securities, after paying or making reasonable provision to pay all claims and obligations of the Trust in accordance with Section 3808(e) of the Business Trust Act, an amount equal to the aggregate of the stated liquidation amount of $25 per Security plus accrued and unpaid Distributions thereon to the date of payment (such amount being the "Liquidation Distribution"), unless, in connection with such dissolution, winding-up or termination, Subordinated Notes in an aggregate principal amount equal to the aggregate stated liquidation amount of such Securities, with an interest rate equal to the Coupon Rate of, and bearing accrued and unpaid interest in an amount equal to the accrued and unpaid Distributions on, such Securities, shall be distributed on a Pro Rata basis to the Holders of the Securities in exchange for such Securities, after paying or making reasonable provision to pay all claims and obligations of the Trust in accordance with Section 3808(e) of the Business Trust Act. If, upon any such dissolution, the Liquidation Distribution can be paid only in part because the Trust has insufficient assets available to pay in full the aggregate Liquidation Distribution, then the amounts payable directly by the Trust on the Securities shall be paid on a Pro Rata basis. 4. Redemption and Distribution. --------------------------- a. Upon the repayment of the Subordinated Notes in whole or in part, whether at maturity or upon redemption, the proceeds from such repayment or payment shall be simultaneously applied to redeem Securities having an aggregate liquidation amount equal to the aggregate principal amount of the Subordinated Notes so repaid or redeemed, at the redemption price for the Subordinated Notes, payable in cash (the "Redemption Price"). Holders will be given not less than 30 nor more than 60 days notice of such redemption. b. If fewer than all the outstanding Securities are to be so redeemed, the Common Securities and the Preferred Securities will be redeemed Pro Rata and the Preferred Securities to be redeemed will be as described in Paragraph 4(h)(ii) below. c. The Subordinated Notes are redeemable, in whole or in part, at the option of the Subordinated Notes Issuer, on one or more occasions, at any time on or after January 20, 2004, at a redemption price equal to 100% of the principal amount per Subordinated Note, plus, in each case, accrued and unpaid interest thereon at the date of the redemption for the Subordinated Notes. A-3

d. If, at any time, a Tax Event or an Investment Company Event (each as defined below, and each a "Special Event") shall occur and be continuing, the Subordinated Notes Issuer shall have the right, upon not less than 30 nor more than 60 days notice, to redeem the Subordinated Notes in whole or in part, for cash within 90 days following the occurrence of such Special Event, at a redemption price equal to 100% of the principal amount to be redeemed plus any accrued and unpaid interest thereon to the date of such redemption and, following such redemption, Securities with an aggregate liquidation amount equal to the aggregate principal amount of the Subordinated Notes so redeemed shall be redeemed by the Trust at the Redemption Price on a Pro Rata basis in accordance with paragraph 8 hereof. The Common Securities will be redeemed Pro Rata with the Preferred Securities, except that if an Event of Default has occurred and is continuing, the Preferred Securities will have priority over the Common Securities with respect to payment of the Redemption Price. e. The following terms used herein shall be defined as follows: (i) "Investment Company Event" means that the Trust shall have received an opinion of counsel experienced in practice under the Investment Company Act to the effect that, as a result of the occurrence of a change in law or regulation or a change in interpretation or application of law or regulation by any legislative body, court, governmental agency or regulatory authority (a "Change in 1940 Act Law"), there is more than an insubstantial risk that the Trust is or will be considered an Investment Company which is required to be registered under the Investment Company Act, which Change in 1940 Act Law becomes effective on or after the date of the Prospectus Supplement. (ii) "Tax Event" means that the Trust shall have received an opinion of counsel experienced in such matters to the effect that on or after the date of the Prospectus Supplement, as a result of (a) any amendment to, or change (including any announced proposed change) in, the laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein, or (b) any official or administrative pronouncement or action, or judicial decision, interpreting or applying such laws or regulations, where such change or amendment becomes effective, or such pronouncement, action or decision is announced or occurs, in each case on or after the date of the Prospectus Supplement, there is more than an insubstantial risk that (i) the Trust is or will be within 90 days of the date of such opinion, subject to United States federal income tax with respect to interest accrued or received on the Subordinated Notes, (ii) the Trust is, or will be within 90 days of the date of such opinion, subject to more than a minimal amount of other taxes, duties, assessments or other governmental charges, or (iii) interest payable by the Subordinated Notes Issuer to the Trust on the Subordinated Notes is not, or within 90 days of the date of such opinion will not be, deductible, in whole or in part, by the Subordinated Notes Issuer for United States federal income tax purposes. f. The Trust may not redeem fewer than all the outstanding Securities unless all accrued and unpaid Distributions have been paid on all Securities for all quarterly Distribution periods terminating on or before the date of redemption. A-4

g. In the event that the Sponsor makes the election referred to in Section 8.1(a)(v) of the Declaration, the Regular Trustees shall dissolve the Trust and, after paying or making reasonable provision to pay all claims and obligations of the Trust in accordance with Section 3808(e) of the Business Trust Act, cause Subordinated Notes, held by the Property Trustee, having an aggregate stated liquidation amount of, with an interest rate identical to the Coupon Rate of, and accrued and unpaid interest equal to accrued and unpaid Distributions on and having the same record date for payment, as the Securities, to be distributed to the Holders of the Securities in liquidation of such Holders' interests in the Trust on a Pro Rata basis in accordance with paragraph 8 hereof. On and from the date fixed by the Regular Trustees for any distribution of Subordinated Notes and dissolution of the Trust: (i) the Securities will no longer be deemed to be outstanding, (ii) The Depository Trust Company (the "Depository") or its nominee (or any successor Clearing Agency or its nominee), as the record Holder of the Preferred Securities, will receive a registered global certificate or certificates representing the Subordinated Notes to be delivered upon such distribution and (iii) any certificates representing Securities, except for certificates representing Preferred Securities held by the Depository or its nominee (or any successor Clearing Agency or its nominee), will be deemed to represent beneficial interests in the Subordinated Notes having an aggregate principal amount equal to the aggregate stated liquidation amount of, with an interest rate identical to the Coupon Rate of, and accrued and unpaid interest equal to accrued and unpaid Distributions on such Securities until such certificates are presented to the Subordinated Notes Issuer or its agent for transfer or reissue. If the Subordinated Notes are distributed to Holders of the Securities, pursuant to the terms of the Indenture, the Subordinated Notes Issuer will use its best efforts to have the Subordinated Notes listed on the New York Stock Exchange or on such other exchange as the Preferred Securities were listed immediately prior to the distribution of the Subordinated Notes. h. Redemption or Distribution Procedures. ------------------------------------- (i) Notice of any redemption of, or notice of distribution of Subordinated Notes in exchange for the Securities (a "Redemption/Distribution Notice") will be given by the Trust by mail to each Holder of Securities to be redeemed or exchanged not fewer than 30 nor more than 60 days before the date fixed for redemption or exchange thereof which, in the case of a redemption, will be the date fixed for redemption of the Subordinated Notes. For purposes of the calculation of the date of redemption or exchange and the dates on which notices are given pursuant to this paragraph 4(h)(i), a Redemption/Distribution Notice shall be deemed to be given on the day such notice is first mailed, by first-class mail, postage prepaid, to Holders of Securities. Each Redemption/Distribution Notice shall be addressed to the Holders of Securities at the address of each such Holder appearing in the books and records of the Trust. No defect in the Redemption/Distribution Notice or in the mailing of either thereof with respect to any Holder shall affect the validity of the redemption or exchange proceedings with respect to any other Holder. (ii) In the event that fewer than all the outstanding Securities are to be redeemed, the Securities to be redeemed will be redeemed Pro Rata from each Holder of Securities, it being understood that, in respect of Preferred Securities registered in the name of and held of record by the Depository (or any successor Clearing Agency) or any other nominee, the distribution of the proceeds of such redemption will be made to each Clearing Agency A-5

Participant (or person on whose behalf such nominee holds such securities) in accordance with the procedures applied by such agency or nominee. (iii) If Securities are to be redeemed and the Trust gives a Redemption/Distribution Notice which notice may only be issued if the Subordinated Notes are redeemed as set out in this paragraph 4 (which notice will be irrevocable) then (A) while the Preferred Securities are in book entry only form, with respect to the Preferred Securities, by 12:00 noon, New York City time, on the redemption date, provided that the Subordinated Notes Issuer has paid the Property Trustee a sufficient amount of cash in connection with the related redemption or maturity of the Subordinated Notes, the Property Trustee will deposit irrevocably with the Depository (or successor Clearing Agency) funds sufficient to pay the Redemption Price with respect to the Preferred Securities and will give the Depository irrevocable instructions and authority to pay the Redemption Price to the Holders of the Preferred Securities, and (B) if the Preferred Securities are issued in definitive form, with respect to the Preferred Securities, and with respect to the Common Securities, provided that the Subordinated Notes Issuer has paid the Property Trustee a sufficient amount of cash in connection with the related redemption or maturity of the Subordinated Notes, the Property Trustee will pay the Redemption Price to the Holders of such Securities by check mailed to the address of the relevant Holder appearing on the books and records of the Trust on the redemption date. If a Redemption/Distribution Notice shall have been given and funds deposited as required, if applicable, then immediately prior to the close of business on the date of such deposit, or on the redemption date, as applicable, Distributions will cease to accrue on the Securities so called for redemption and all rights of Holders of such Securities so called for redemption will cease, except the right of the Holders of such Securities to receive the Redemption Price, but without interest on such Redemption Price. Neither the Regular Trustees nor the Trust shall be required to register or cause to be registered the transfer of any Securities which have been so called for redemption. If any date fixed for redemption of Securities is not a Business Day, then payment of the Redemption Price payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day falls in the next calendar year, such payment will be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date fixed for redemption. If payment of the Redemption Price in respect of Securities is improperly withheld or refused and not paid either by the Property Trustee or by the Sponsor as guarantor pursuant to the relevant Securities Guarantee, Distributions on such Securities will continue to accrue, from the original redemption date to the actual date of payment, in which case the actual payment date will be considered the date fixed for redemption for purposes of calculating the Redemption Price. (iv) Redemption/Distribution Notices shall be sent by the Regular Trustees on behalf of the Trust to (A) in respect of the Preferred Securities, the Depository or its nominee (or any successor Clearing Agency or its nominee) if the Global Certificates have been issued or if Definitive Preferred Security Certificates have been issued, to the Holder thereof, and (B) in respect of the Common Securities, to the Holder thereof. (v) Subject to the foregoing and applicable law (including, without limitation, United States federal securities laws), provided the acquiror is not the Holder of the Common Securities or the obligor under the Indenture, the Sponsor or any of its subsidiaries may A-6

at any time and from time to time purchase outstanding Preferred Securities by tender, in the open market or by private agreement. 5. Voting Rights Applicable to Preferred Securities. ------------------------------------------------ a. Except as provided under paragraphs 5(b) and 7 and as otherwise required by law and the Declaration, the Holders of the Preferred Securities will have no voting rights. b. Subject to the requirements of the third to last sentence of this paragraph, the Holders of a Majority in liquidation amount of the Preferred Securities, voting separately as a class, may direct the time, method, and place of conducting any proceeding for any remedy available to the Property Trustee, or exercising any trust or power conferred upon the Property Trustee under the Declaration, including (i) directing the time, method, and place of conducting any proceeding for any remedy available to the Subordinated Notes Trustee, or exercising any trust or power conferred on the Subordinated Notes Trustee with respect to the Subordinated Notes, (ii) waiving any past default and its consequences that is waivable under Section 513 of the Indenture, (iii) exercising any right to rescind or annul a declaration that the principal of all the Subordinated Notes shall be due and payable or (iv) consenting to any amendment, modification or termination of the Indenture or the Subordinated Notes where such consent shall be required, provided, however, that where a consent under the Indenture would require the consent or act of the Holders of greater than a majority in principal amount of Subordinated Notes affected thereby (a "Super Majority"), the Property Trustee may only give such consent or take such action at the direction of the Holders of at least the proportion in liquidation amount of the Preferred Securities which the relevant Super Majority represents of the aggregate principal amount of the Subordinated Notes outstanding. The Property Trustee shall not revoke any action previously authorized or approved by a vote of the Holders of the Preferred Securities. Other than with respect to directing the time, method and place of conducting any remedy available to the Property Trustee or the Subordinated Notes Trustee as set forth above, the Property Trustee shall not take any action in accordance with the directions of the Holders of the Preferred Securities under this paragraph unless the Property Trustee has obtained an opinion of counsel to the effect that for the purposes of United States federal income tax the Trust will not be classified as other than a grantor trust on account of such action. If the Property Trustee fails to enforce its rights under the Declaration, any Holder of Preferred Securities may institute a legal proceeding directly against any Person to enforce the Property Trustee's rights under the Declaration, without first instituting a legal proceeding against the Property Trustee or any other Person. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing with respect to the Preferred Securities and such event is attributable to the failure of the Subordinated Notes Issuer to pay interest, premium, if any, or principal on the Subordinated Notes on the date such interest, premium, if any, or principal is otherwise payable (or in the case of redemption, on the redemption date), then a holder of Preferred Securities may institute a Direct Action for enforcement of payment to such holder of the principal of, premium, if any, or interest on, Subordinated Notes having a principal amount equal to the aggregate liquidation amount of the Preferred Securities of such holder on or after the respective due date specified in the Subordinated Notes. Notwithstanding any payments made to such Holder of Preferred Securities by the Subordinated Notes Issuer in connection with a Direct Action, the Subordinated Notes Issuer shall remain obligated to pay the principal of, premium, if any, and interest on the Subordinated Notes held by the Trust or the Property Trustee, and the Subordinated Notes Issuer A-7

shall be subrogated to the rights of the Holder of such Preferred Securities with respect to payments on the Preferred Securities to the extent of any payment made by the Subordinated Notes Issuer to such Holder in any Direct Action. Except as provided in the preceding sentences, the Holders of Preferred Securities will not be able to exercise directly any other remedy available to the holders of the Subordinated Notes. c. Any approval or direction of Holders of Preferred Securities may be given at a separate meeting of Holders of Preferred Securities convened for such purpose, at a meeting of all of the Holders of Securities in the Trust or pursuant to written consent. The Regular Trustees will cause a notice of any meeting at which Holders of Preferred Securities are entitled to vote, or of any matter upon which action by written consent of such Holders is to be taken, to be mailed to each Holder of record of Preferred Securities. Each such notice will include a statement setting forth (i) the date of such meeting or the date by which such action is to be taken, (ii) a description of any resolution proposed for adoption at such meeting on which such Holders are entitled to vote or of such matter upon which written consent is sought and (iii) instructions for the delivery of proxies or consents. d. No vote or consent of the Holders of the Preferred Securities will be required for the Trust to redeem and cancel Preferred Securities or to distribute the Subordinated Notes in accordance with the Declaration and the terms of the Securities. e. Notwithstanding that Holders of Preferred Securities are entitled to vote or consent under any of the circumstances described above, any of the Preferred Securities that are owned by the Sponsor or any Affiliate of the Sponsor shall not be entitled to vote or consent and shall, for purposes of such vote or consent, be treated as if they were not outstanding. 6. Voting Rights With Respect to Common Securities. ----------------------------------------------- a. Except as provided under paragraphs 6(b), 6(c) and 7 and as otherwise required by law and the Declaration, the Holders of the Common Securities will have no voting rights. b. The Holders of the Common Securities are entitled, in accordance with Article V of the Declaration, to vote to appoint, remove or replace any Trustee or to increase or decrease the number of Trustees. c. Subject to Section 2.6 of the Declaration and only after all Events of Default with respect to the Preferred Securities have been cured, waived or otherwise eliminated and subject to the requirements of the second to last sentence of this paragraph, the Holders of a Majority in liquidation amount of the Common Securities, voting separately as a class, may direct the time, method, and place of conducting any proceeding for any remedy available to the Property Trustee, or exercising any trust or power conferred upon the Property Trustee under the Declaration, including (i) directing the time, method, place of conducting any proceeding for any remedy available to the Subordinated Notes Trustee, or exercising any trust or power conferred on the Subordinated Notes Trustee with respect to the Subordinated Notes, (ii) waiving any past default and its consequences that is waivable under Section 513 of the Indenture, or (iii) exercising any right to rescind or annul a declaration that the principal of all the Subordinated A-8

Notes shall be due and payable, provided, however, that where a consent or action under the Indenture would require the consent or act of the Holders of greater than a majority in principal amount of Subordinated Notes affected thereby (a "Super Majority"), the Property Trustee may only give such consent or take such action at the direction of the Holders of at least the proportion in liquidation amount of the Common Securities which the relevant Super Majority represents of the aggregate principal amount of the Subordinated Notes outstanding. Pursuant to this paragraph 6(c), the Property Trustee shall not revoke any action previously authorized or approved by a vote of the Holders of the Common Securities. Other than with respect to directing the time, method and place of conducting any remedy available to the Property Trustee or the Subordinated Notes Trustee as set forth above, the Property Trustee shall not take any action in accordance with the directions of the Holders of the Common Securities under this paragraph unless the Property Trustee has obtained an opinion of counsel to the effect that for the purposes of United States federal income tax the Trust will not be classified as other than a grantor trust on account of such action. If the Property Trustee fails to enforce its rights under the Declaration, any Holder of Common Securities may, to the fullest extent permitted by law, institute a legal proceeding directly against any Person to enforce the Property Trustee's rights under the Declaration, without first instituting a legal proceeding against the Property Trustee or any other Person. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing with respect to the Common Securities and such event is attributable to the failure of the Subordinated Notes Issuer to pay interest or principal on the Subordinated Notes on the date such interest or principal is otherwise payable (or in the case of redemption, on the redemption date), then a holder of Common Securities may institute a proceeding for enforcement of payment to such holder of the principal of, or interest on, Subordinated Notes having a principal amount equal to the aggregate liquidation amount of the Common Securities of such holder on or after the respective due date specified in the Subordinated Notes. d. Any approval or direction of Holders of Common Securities may be given at a separate meeting of Holders of Common Securities convened for such purpose, at a meeting of all of the Holders of Securities in the Trust or pursuant to written consent. The Regular Trustees will cause a notice of any meeting at which Holders of Common Securities are entitled to vote, or of any matter upon which action by written consent of such Holders is to be taken, to be mailed to each Holder of record of Common Securities. Each such notice will include a statement setting forth (i) the date of such meeting or the date by which such action is to be taken, (ii) a description of any resolution proposed for adoption at such meeting on which such Holders are entitled to vote or of such matter upon which written consent is sought and (iii) instructions for the delivery of proxies or consents. e. No vote or consent of the Holders of the Common Securities will be required for the Trust to redeem and cancel Common Securities or to distribute the Subordinated Notes in accordance with the Declaration and the terms of the Securities. 7.

dissolution, winding-up or termination of the Trust, other than as described in Section 8.1 or Section 3.14 of the Declaration, then the Holders of outstanding Securities as a class, will be entitled to vote on such amendment or proposal (but not on any other amendment or proposal) and such amendment or proposal shall not be effective except with the approval of the Holders of at least a Majority in liquidation amount of the Securities, voting together as a single class; provided, however, that if any amendment or proposal referred to in clause (i) above would adversely affect only the Preferred Securities or the Common Securities, then only the affected class will be entitled to vote on such amendment or proposal and such amendment or proposal shall not be effective except with the approval of a Majority in liquidation amount of such class of Securities. b. In the event the consent of the Property Trustee as the holder of the Subordinated Notes is required under the Indenture with respect to any amendment, modification or termination of the Indenture or the Subordinated Notes, the Property Trustee shall request the direction of the Holders of the Securities with respect to such amendment, modification or termination and shall vote with respect to such amendment, modification or termination as directed by a Majority in liquidation amount of the Securities voting together as a single class; provided, however, that where a consent under the Indenture would require the consent of the Holders of greater than a majority in aggregate principal amount of the Subordinated Notes (a "Super Majority"), the Property Trustee may only give such consent at the direction of the Holders of at least the proportion in liquidation amount of the Securities which the relevant Super Majority represents of the aggregate principal amount of the Subordinated Notes outstanding; provided, further, that the Property Trustee shall not take any action in accordance with the directions of the Holders of the Securities under this paragraph 7(b) unless the Property Trustee has been furnished an opinion of counsel to the effect that for the purposes of United States federal income tax the Trust will not be classified as other than a grantor trust on account of such action. 8. Pro Rata. -------- A reference in these terms of the Securities to any payment, distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder of Securities according to the aggregate liquidation amount of the Securities held by the relevant Holder in relation to the aggregate liquidation amount of all Securities outstanding unless, in relation to a payment, an Event of Default under the Indenture has occurred and is continuing, in which case any funds available to make such payment shall be paid first to each Holder of the Preferred Securities pro rata according to the aggregate liquidation amount of Preferred Securities held by the relevant Holder relative to the aggregate liquidation amount of all Preferred Securities outstanding, and only after satisfaction of all amounts owed to the Holders of the Preferred Securities, to each Holder of Common Securities pro rata according to the aggregate liquidation amount of Common Securities held by the relevant Holder relative to the aggregate liquidation amount of all Common Securities outstanding. 9.
